Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are referred
to as options. Replacement parts approved for customer installation are referred to as Customer
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for
customers to install options or replace CRUs. You must closely follow all instructions when installing or
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a
product are zero. Before you remove the covers from a product equipped with a power cord, always ensure
that the power is turned off and that the product is unplugged from any power source. If you have any
questions or concerns, contact the Customer Support Center.
Although there are no moving parts in your computer after the power cord has been disconnected, the

Ergonomic information
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that
you perform. In addition, use healthy work habits to maximize your performance and comfort when using
your computer.
Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the
surrounding light sources, active seating, and the placement of your computer hardware, can help you
improve your performance and achieve greater comfort.
This example shows someone in a conventional setting. Even when not in such a setting, you can follow
many of these tips. Develop good habits, and they will serve you well.
General posture: Make minor modifications in your working posture to deter the onset of discomfort caused
by long periods of working in the same position. Frequent short breaks from your work also help to prevent
minor discomfort associated with your working posture.
Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to
30 inches). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep
the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press the
brightness control keys to adjust display brightness.
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
© Copyright Lenovo 2020 45
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your comfort posture.
Arm and hand position: If available, use chair arm rests or an area on your working surface to provide
weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)
position. Type with a soft touch without pounding the keys.
Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
What if you are traveling?
It might not be possible to observe the best ergonomic practices when you are using your computer while on
the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible.
Sitting properly and using adequate lighting, for example, helps you maintain desirable levels of comfort and
performance. If your work area is not in an office setting, ensure to take special note of employing active
sitting and taking work breaks. Many product solutions are available to help you modify and expand your
computer to best suit your needs. You can find some of these options at https://www.lenovo.com/accessories.
Explore your options for docking solutions and external products that provide the adjustability and features
that you want.
Questions about vision?
The visual display screens of notebook computers are designed to meet the highest standards. These visual
display screens provide you with clear, crisp images and large, bright displays that are easy to see, yet easy
on the eyes. Any concentrated and sustained visual activity can be tiring. If you have questions on eye
fatigue or visual discomfort, consult a vision-care specialist for advice.
Basic maintenance tips
• Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers
(more than 13 cm or 5 inches).
• Avoid subjecting your computer to extreme temperatures (below 5 ℃/41 ℉ or above 35 ℃/95 ℉).
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.
• Do not turn your computer over when the ac power adapter is plugged in, otherwise, it could break the
adapter plug.
• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect
cords and cables.
• When picking up your open notebook computer, hold it by the bottom. Do not pick up or hold your
notebook computer by the display.
• Avoid directly exposing your computer and peripherals to the air from an appliance that can produce
negative ions. Wherever possible, ground your computer to facilitate safe electrostatic discharge.
Cleaning your computer
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
Cleaning the computer cover
Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying liquids directly to the cover.
Cleaning the keyboard
Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If you wipe several keys at
a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid spraying cleaner directly
46 User Guide
onto the keyboard. To remove any crumbs or dust from beneath the keys, you can use a camera blower with
a brush or use cool air from a hair dryer.
Cleaning the computer screen
Scratches, oil, dust, chemicals, and ultraviolet light can affect the performance of your computer screen. Use
a dry, soft, lint-free cloth to wipe the screen gently. If you see a scratch-like mark on your screen, it might be
a stain. Wipe or dust the stain gently with a soft, dry cloth. If the stain remains, moisten a soft, lint-free cloth
with water or eyeglass cleaner, but do not apply liquids directly to your computer screen. Ensure that the
computer screen is dry before closing it.
